Goggles are forms of protective eyewear that usually enclose or protect the eye area in order to prevent particulates, infectious fluids, or chemicals from striking the eyes. For example, when swimming, goggles protect the eyes from salt or chlorine in the water.

The human eye is sensitive to intense light because it damages the retina and can even blind the individual. There are many different types of eye protection against light suited for different applications.

The most common forms of eye protection against light are sunglasses. These primarily protect against UV light from the sun and help increase visibility in bright conditions. They often tend to be fashionable as well as practical. Laser protection eyewear is similar but will filter out a particular (or small range of) wavelength(s), customized to the laser being viewed. Laser protection eyewear is particularly important because of the extremely high intensity of laser light.
